Coming soon: SPG will roll out a revolutionary new program that puts the power of your room key on your mobile device.

Soon Starwood Preferred Guest® members can open their hotel room from their SPG App — no extra baggage. Consider this one more key to a better stay.

After installing the Starwood Preferred Guest (SGP) App, guests will receive a virtual key on their iPhone, which can then be used to unlock a door with a tap using Bluetooth 4.0. The newer Bluetooth specification, first introduced with the iPhone 4s, has been used in a similar way for many home locking products like the Lockitron and the August Smart Lock, but this is the first time it's being used on a larger scale.

Starwood officials are betting that the technology will become the standard for hotels in the future, replacing traditional hotel check-in methods.

"We believe this will become the new standard for how people will want to enter a hotel," says Frits van Paasschen, Starwood's CEO. "It may be a novelty at first, but we think it will become table stakes for managing a hotel."
